I am using the example of the song "More Than Words" by Extreme to illustrate my question.
https://tabs.ultimate-guitar.com/e/extreme/more_than_words_crd.htm
I see both the chords C
and Cm
being used in the same line (line 9). I was unaware of the theory behind this. I have come across a "Picardy Third" in some music before, and that concept somewhat makes sense to me. But I don't think a "Picardy Third" applies here, or maybe I just can't see it.
In addition to this usage of the IV and iv chord, the song also uses the chords G
and G7
. This usage of both the I and I7 chords doesn't make sense to me either, because the key of the song looks to be in G
.
I would appreciate it if anyone can explain this to me.
